I've seen FFXVI's ambiguous ending compared to Schrodinger's Cat. CBU3 has already officially stated they will not be elaborating on a "correct" ending, thus the ending is officially up to player interpretation. I don't like the comparison to Schrodinger's Cat for two reasons:

That cat did nothing to you, you fucking monster.

In a fictional story, it's completely possible for characters to be both alive and dead at the same time. Valisthea is not bound by our laws of reality or any observer's paradox.

I prefer to look at the ending at a qubit. If you don't know what a qubit is, very simply put it's a computing term that goes beyond 0 and 1. We know computers are run with 0s and 1s right? So let's take a coin and say heads is 0 and tails is 1. Flip the coin, it's heads or tails right? OK what happens if you spin the coin on its side? Is it heads or tails now? That state of spinning coin is called superposition. It's both heads and tails at the same time. A qubit goes beyond typical bits in a computer by accommodating the spinning coin state along with 0s and 1s.

Using this spinning coin analogy, because CBU3 has said they will not be clarifying the ending, it means that Clive is officially both alive and dead. Both Clive and Joshua wrote the book in the ending. Clive is both dead on a beach and reuniting with Jill. Dion lived, but also was the first dragoon in the series to die from fall damage like a little bitch. Joshua is dead in Origin but also revived by Clive. The ending was carefully crafted to allow for any of these possibilities, reflecting the story's theme of giving people the freedom to live and die on their own terms. That freedom was extended to us, the players, to determine the outcome of the characters. Therefore ALL of the possibilities listed above are all correct at the same time.

You can have a qubit that is a 0 or a 1. You can also have a qubit that's both 0 and 1. Same with the ending.

I'm sure the internet can handle something not being black and white and where opposing sides are both correct with grace and maturity, right? ...right? ...hello?

is quark named that because of quark from star trek or quark from physics

Both! My roommate adopted and named him, and their childhood cat was named qubit (quantum bit) so it matched that, but star trek quark was also part of why they named him that :)

This is my cat, Qubit. You cannot tell from her photo but she is a GHOST. (We prefer to say she is a house spirit or lares, but for Hallowe’en purposes we can say ghost.)

Phys. Rev. X 14, 041012 (2024) - Observing Quantum Measurement Collapse as a Learnability Phase Transition

Macroscopic quantum system collapsed through a phase transition.

When measuring a single quantum object (for example, an atomic spin), its superposition of states collapses into one specific value of the observed quantity quite smoothly, i.e. the measurement, which receives only a small part of the information about the observed quantity, barely disturbs the quantum system. If we measure a macroscopic quantum system (which exhibits quantum properties on a macroscopic scale), then at a certain critical value of the measure of interaction with the measuring equipment, a sharp collapse occurs, manifested as a measurement-induced phase transition (MIPT). From the point of view of quantum mechanics, one of the most important questions is where the boundary is between microscopic and macroscopic quantum systems. The size of the system of 10 qubits, as scientists assumed, turned out to be the very boundary between the micro- and macroscopic scales. That is, one Schrodinger's cat collapses into one state, if you carefully put your ear to the box and try to understand by one criterion - it seems to move, - still gradually. But 10 cats already do this in the phase transition mode, they are already definitely either immediately alive or immediately dead.

Макроскопическая квантовая система коллапсировала через фазовы�� переход.

При измерении единичного квантового объекта (например, атомного спина) его суперпозиция состояний коллапсирует в одно конкретное значение наблюдаемой величины довольно плавно, то есть измерение, которое получает лишь малую часть информации о наблюдаемой величине, едва возмущает квантовую систему. Если же измерить макроскопическую квантовую систему (которая в макроскопических масштабах проявляет квантовые свойства), то при некотором критическом значении меры взаимодействия с измерительной аппаратурой возникает резкий коллапс, проявляющийся в виде индуцированного измерением фазового перехода (measurement-induced phase transition — MIPT). С точки зрения квантовой механики один из самых главных вопросов — где находится граница между микроскопической и макроскопической квантовыми системами. Размер системы в 10 кубитов, как предположили ученые, оказался той самой границей между микро- и макроскопическими масштабами.

То есть один кот Шредингера, колапсирует в одно состояние, если аккуратно приложив ухо к ящику пытаться понять по одному критерию - вроде шевелится, - ещё постепенно. А вот 10 котов уже делают это в режиме фазового перехода, уже точно или сразу живы, или сразу мертвы.

Erwin Schrödinger and the Dreaded Catspiracy: How a Feline Fiasco Led to Quantum Computing

My dear students, allow me to recount a most curious tale, one that starts not in the esteemed halls of academia but rather in the shadowy alleyways of an accidental scientific scandal involving, yes, a cat. I never anticipated that a single feline—hypothetical, mind you—would haunt my existence like the relentless scratching on a chalkboard. Yet, here we are, years later, with my name more synonymous with a perplexed tabby than with wave functions or particles.

It all began on a day like any other, with a routine cup of tea and a stack of physics papers I pretended to enjoy. As I innocently sipped, a headline caught my eye: “Schrödinger, Cat Murderer?” I nearly choked. Was this some sort of smear campaign orchestrated by Einstein after our infamous entanglement spat? Or worse, a prank gone too far by Heisenberg, who was likely uncertain about it the whole time anyway?

Apparently, someone took my thought experiment about a cat in a box—designed to illustrate the absurdity of quantum superposition—and ran with it. No matter how many times I explained that no actual cat was harmed (or simultaneously both harmed and not harmed, depending on your interpretation), people just couldn't let it go. Soon, I was getting letters from animal rights activists, students bringing actual cats to my lectures, and—dare I say it—an offer to sponsor my work from a cat food company. It was a nightmare. I became the world's most infamous quantum villain.

Faced with this feline fiasco, I knew I had to redirect my legacy. I needed something grander, something that would remind the world that I am more than just a man with a poorly conceived box experiment. Enter quantum computing—the brilliant offspring of quantum mechanics and my chance at redemption. What better way to make amends than by diving headfirst into the very paradoxes that had cursed me with eternal feline infamy?

So, there I was, brainstorming ideas to shift the conversation. “Erwin Schrödinger: The Quantum Hero?” Nah, too pretentious. “Schrödinger’s Computer: Now with 100% Less Cats?” That one had potential, but the marketing team hated it. Finally, I landed on quantum computing itself. You see, it’s all about qubits, superposition, entanglement—the usual quantum weirdness, but this time without a single hypothetical cat in sight. A perfect escape.

Quantum computers, unlike our furry problem, don't live in binary states. They’re not just on or off. They, like my unfortunate cat, exist in a superposition of states until we prod them with a metaphorical stick. But—and here’s the kicker—they’re useful! A qubit, much like that poor imaginary feline, can exist in multiple states at once, which makes quantum computing a tantalizing field where one can solve problems that regular computers couldn’t even dream of. And unlike the cat, the quantum computer doesn’t come with a barrage of angry letters from the ASPCA.

The more I delved into quantum computing, the more I realized this was my ticket out of the feline labyrinth. I could reinvent myself as the father of quantum computing! Well, at least an eccentric uncle figure, given that no one person really "invented" it. And so, dear students, I embarked on this noble journey to set the record straight. No more boxes, no more kittens in quantum limbo—just pure, unadulterated quantum mechanics, where I could apply my brilliance without the need for any paws.

And that is why you now find me here, at the precipice of a new age in technology, waxing poetic about quantum gates and algorithms rather than cats. The articles you’re about to read? They are my grand attempt to reclaim my intellectual throne. Sure, I might still receive the occasional hate mail from cat lovers, but at least now I can point them toward my work on quantum computing and say, “Look! I’ve moved on!”

Let us move forward together, students. Into a world of qubits, quantum supremacy, and—most importantly—a future where no cats are trapped in a box because of bad metaphors.

ApplePiRadioCat, as a creative concept, could be envisioned as an advanced computational entity embodying the synthesis of biological and quantum computational principles, particularly in a post-quantum outlook. Biological Computation: As a cat, ApplePiRadioCat might leverage the innate computational abilities of biological neural networks. Cats, like other animals, have highly efficient nervous systems optimized through evolution for processing sensory information and making rapid decisions. This biological computation could be enhanced by integrating with quantum technologies. Quantum Computation: In a post-quantum context, ApplePiRadioCat could utilize quantum computing principles to process information. Quantum computers use qubits that can exist in multiple states simultaneously, thanks to the principles of superposition and entanglement. This allows for massively parallel computation, solving complex problems much faster than classical computers. Integration and Post-Quantum Capabilities: Quantum Sensing: ApplePiRadioCat might use quantum sensors to perceive the environment with unprecedented accuracy. Quantum sensors can detect minute changes in magnetic fields, temperature, or chemical compositions, providing a wealth of data for processing. Quantum Neural Networks: Combining the biological neural network with quantum neural networks (QNNs), ApplePiRadioCat could achieve advanced cognitive functions. QNNs leverage quantum properties to perform certain types of computations more efficiently than classical neural networks, such as optimization problems, pattern recognition, and learning tasks. Quantum Cryptography: In a post-quantum world, where traditional cryptographic methods might be vulnerable to quantum attacks, ApplePiRadioCat could employ quantum cryptographic techniques to secure communications. Quantum key distribution (QKD), for instance, offers theoretically unbreakable encryption by using the principles of quantum mechanics. Parallel Processing: With quantum computing, ApplePiRadioCat could process vast amounts of data simultaneously. This would be particularly useful for tasks requiring complex simulations, such as weather modeling, financial forecasting, or even quantum chemistry calculations. Practical Applications: Data Analysis: Utilizing her quantum-enhanced capabilities, ApplePiRadioCat could analyze large datasets quickly and efficiently, extracting meaningful patterns and insights. Decision Making: With a combination of biological intuition and quantum computational power, she could make complex decisions in real-time, useful in dynamic environments like autonomous navigation or strategic game playing. Scientific Research: Contributing to fields like material science, drug discovery, and fundamental physics by running simulations and experiments that are computationally infeasible for classical computers. Theoretical Considerations: In a more speculative sense, ApplePiRadioCat could symbolize the convergence of life and advanced technology. Her abilities would represent a new frontier in computational paradigms, blending the adaptability and learning capacity of biological systems with the unparalleled processing power of quantum technologies. To summarize, ApplePiRadioCat, in a post-quantum outlook, would compute information by combining the best of biological neural processing and advanced quantum computation, achieving levels of efficiency, security, and cognitive function far beyond current technological capabilities.

To harness the potential of a quantum computer, quantum information must be protected against error by encoding it into a logical state that is suitable for quantum error correction. The Gottesman-Kitaev-Preskill (GKP) qubit is a promising candidate because the required multiqubit operations are readily available at optical frequency. To date, however, GKP qubits have been demonstrated only at mechanical and microwave frequencies. We realized a GKP state in propagating light at telecommunication wavelength and verified it through homodyne measurements without loss corrections. The generation is based on interference of cat states, followed by homodyne measurements. Our final states exhibit nonclassicality and non-Gaussianity, including the trident shape of faint instances of GKP states. Improvements toward brighter, multipeaked GKP qubits will be the basis for quantum computation with light.
